| Outline of Final Research Achievements |
Hydorgen sulfide, a toxic volcanic gas, functions as a gaseous physiological and pathophysiological molecule similar to other ones, such as a carbon monoxide and a nitric monoxide. In this study, we demonstrated that the acidic condition enhanced the diffusion of hydrogen sulfide into the cytosol and the activation of TRPA1, a nociceptor. In addition, hydrogen sulfide enhanced and/or attenuated the spontaneous excitatory postsynaptic currents in lamina II neurons in spinal cord slices. These results suggest that the regulation of hydrogen sulfide production may be a target for a development of analgesic drugs.
